[0002] The temperature-resistant film plastic woven bag is a kind of plastic woven bag treated specially, which has good temperature resistance and protection function. This bag is usually used for packaging and transporting goods (such as chemical fertilizer, chemicals, etc.) that need to be stored and transported under different temperature conditions.

[0003] At different temperatures, the mechanical strength of the temperature-resistant film plastic woven bag is also different. At high temperature, the molecular chain activity of the temperature-resistant film plastic woven bag is enhanced, which softens and deforms the bag body, resulting in a decrease in the mechanical strength of the bag body and affecting its tear resistance, so it cannot hold materials well.

[0004] Therefore, manufacturers need to sample the products of the same batch for strength testing under high temperature conditions before they are shipped. Since the testing environment is high temperature, the technicians are easy to be scalded during the testing process.

[0005] In view of the above problems, we propose a temperature-resistant film plastic woven bag strength testing device. CONTENT OF THE UTILITY MODEL
